when we can't see or perceive visually

Psychology Section #12

Eye disorders are when your vision or what you perceive visually is damaged. A few examples of eye disorders are motion blindness, visual agnosia, blindness, and blindsight. When you have an eye disorder you are constantly in a greater danger than others, whether it is because you cannot see at all, or because you cannot see motion. In these cases you put yourself in danger by walking into the street and not knowing it, or walking down a pier and falling off. Research on these disorders is important because vision is, in my opinion, one of the most important senses we have. I have a personal connection to eye disorders because glaucoma has had a big impact on my family. My grandfather has glaucoma, and they believe my mother may have it as well. Glaucoma can be caused due to eye pressure, or it can be inherited and shows up in adults around the age of 40. I hope that by the time I reach that age there will have been more research conducted in case I am to get it. Also glaucoma is the cause of blindness for 12.3% of all blind people in the world.

The image below is of a woman who was blind in one eye. Looking at the picture her blind eye (the one on the left) changed color after become blind.

Below is an image of an eye with glaucoma, and as you can see it is disgusting looking.

I also found a link on youtube to a video of a man who has blindsight. The man is blind but is still able to walk through an obstacle course without problems.
